No Tachometer and help with spark intensifier

This time I have two problems that need your help…

  1. My tach. is not working I checked easy areas of fuse etc…where do I check under hood to locate the wires that enliven the tack.?? (I assume it must involve the distrib.)
    2.I have a spark intensifier (Lucas) four wires coming out…(I know some go to plus side of coil but where do the others go )??
    Thanks for your help…

I’ve never heard of a “spark intensifier”, and apparently neither has Google.

Ivan, I think your “intensifier” is really your ignition amplifier. The wires grouped together-
One goes to tach.
One goes to ECU.
One goes to + coil,
and one to - coil.
The two other wires twisted together which have a plug go to the pickup on the distributor.

I have !! Decades ago. Various versions. Generaly, “rip offs”.

But, aye, the tach gets it’s “pulses” from the distributor.

Check the S57 wire schematic… Most informative…
